Building Blocks for a Perfect Patio

Precast concrete slabs in terra-cotta, charcoal, and soft gray give this patio its distinctive checkerboard look. For a new installation, purchase slabs like these that are tinted during the manufacturing process. Or to liven up existing monotone slabs, you can brush, trowel, or squeegee on a thin layer of Quikrete's DIY-friendly concrete resurfacer (find it at The Home Depot). | Photo: Norm Plate | thisoldhouse.com
